杰克逊设置默认视图 [英] Jackson set default view

问题描述

// short-cut:
objectMapper.writeValueUsingView(out, beanInstance, ViewsPublic.class);

// or fully exploded:
objectMapper.getSerializationConfig().setSerializationView(Views.Public.class);
// (note: can also pre-construct config object with 'mapper.copySerializationConfig'; reuse)
objectMapper.writeValue(out, beanInstance); // will use active view set via Config

// or, starting with 1.5, more convenient (ObjectWriter is reusable too)
objectMapper.viewWriter(ViewsPublic.class).writeValue(out, beanInstance);

所以我有：

ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);
mapper.getSerializationConfig().setSerializationView(ResourceView.PublicView.class);

不起作用 JavaDoc 1.8.2 说： setSerializationView 已弃用，我必须使用 withView（）

Not works JavaDoc 1.8.2 says: setSerializationView is deprecated, I have to use withView()

ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);
mapper.getSerializationConfig().withView(ResourceView.PublicView.class);

仍然无效。 JavaDoc 2.2.0 表示

Still not working. JavaDoc 2.2.0 says

public SerializationConfig withView （类<？>视图）

从类复制的说明：MapperConfigBase

Description copied from class: MapperConfigBase

构建和返回具有不同视图的新实例的方法。

Method for constructing and returning a new instance with different view to use.

但我不能将新的 SerializationConfig 设置为现有的 ObjectMapper

But I can't set the new SerializationConfig to the existing ObjectMapper

我在服务器端使用Jersey和JAX-RS

I use Jersey and JAX-RS on the server side

推荐答案

使用Jersey我必须将视图设置为 JacksonJsonProvider

With Jersey I had to set the View at the JacksonJsonProvider

ResourceConfig config = new ResourceConfig();
config.packages("com.example.foo");

JacksonJsonProvider jjp = new JacksonJsonProvider();
jjp.setDefaultWriteView(ResourceView.PublicView.class);
config.register(jjp);
